Application: 

The equipment is used to measure the ductility of the materials such as road petroleum asphalt, polymer modified asphalt, liquid petroleum asphalt distillation residue and emulsion asphalt evaporation residue.
Its design is reliable, the operation is concise, in the domestic industry at leading level.

With refrigeration system and micro-processor based digital temperature controller. Ductility is defined as distance in cms to which a standard briquette of bitumen can be stretched before the thread breaks.

The briquette is stretched at a rate of 50 mm/min.± 2.5mm per minute at a temperature of 27°C ± 0.5°C. The Machine is having built in refrigeration system to work a below ambient temperature up to 10°C in tropical conditions. The Machine will operate at 27°C with control accuracy of ± 0.5°C as per the requirement of IS.

The apparatus consists of water bath with a heater, and a circulating pump to maintain uniform water temperature. One half of the briquette moulds is fixed in a fixed plate in the water bath, the other half of the briquette mould is fixed to a carrier which slides over a rotating threaded shaft with a clutch, The motor and gears to rotate the shaft are housed in a cabinet fixed above the other end of the bath. A pointer fixed to the carrier moves over. a scale graduated from 0-100 cm x 1mm fixed on the bath with "0" (Zero) of the scale towards the fixed plates side. The rotating shaft has 2 speeds of travel for the bracket, 5 cm/min.and 1cm/min. selected by a clutch. Water bath inside is of stainless steel with insulation and water drain cock .

A heater with is fitted inside the water bath. The Temp. is controlled by dual display Microprocessor based Auto Tuning PID Digital Temp. indicator cum controller. Control switches for motor, stirrer, heater and indicator lamps are fixed at a
convenient place on the water bath. Complete with three briqutte moulds and one base plate, All supply single phase. As per IS 1208.

Features:

1. The refrigeration system adopts imported components and has a circulating system with stable temperature.
2. High quality stainless steel bottom board with transparent organic glass cover.
3. Using ball screw and linear guide rail group to stretch, the tensile precision is high.
4. The stretching speed is controlled by stepper motor stepless speed adjustment, automatic high speed homing, time-saving and have left-right position limit switch protection.
5. Use color liquid crystal display, clear .
6. automatically record time of test start and test time.
